Specification of Letters Patent.

Patented Aug. 22, 1931,

Application filed September 4, 1914. Serial ITO. 866,232.

To all whom it may concern:

Be it known that I, CHAnLEs A. Lonn- (mun, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Adding and Listing Machines, of which the following is a specification.

The present invention relates to so-called tally-roll attachments or equipments for adding and listing machines and is in the nature 01" an improvement upon the invention of Fred F. Main which has been made the subject of a prior patent issued J anuary 5, 1915, No. 1,123,337.

One object of the present invention is to do away wth a tally-roll carriage constructionwhich requires parts extending laterally beyond the machine proper to unite the sup-- ports for the supply and take-up rolls for the tally strip. Thus-according to my invention the upper and lower roll holders are connected by and unified with a portion of thecarriage extending directly between them, this portion of the carriage being of such character-as to be accommodated in the limited space between the main paper car- 'tion between the same and the tabulating equipment for regulating the lateral shifting of the main carriage manually or in an automatic manner. At the same time I pre-' servethe capacity of the tally-roll equipment'for automatic cooperation withsuch ta-bulating equipment.

With these and incidental objects in View the invention consists in certain novel features of construction and combinations of pa rts, the essential elements whereof are recited in the appended claims and the preferred form of embodiment of which is illustrated in the accompanying drawings, which form a partlof this specification.

'Of such drawings Figure 1 represents in right side elevation an adding and listing machine of the well-known Burroughs type 'having added thereto a tally-roll equip ates a roller platen against i" ment embodying my present invention; Fig. 2 1s a broken out rear elevation of the machine with the tally-roll in non-printing position; Fig. 3 is a rear elevation with the regular carriage equipment omitted and the tally roll in printing position; Fig. 4 is a vertical section on line 4 4: of Fig. 3; Fig. 5 IS a partial top plan view of the machine "with the tally-roll carriage in section and the regular paper carriage equipment omit ted; Fig. 6 IS a vertical section of the lower rear portion of the machine taken substantially on the line G-6 of Fig. 2; Fig. 7 is a. detail sectional view taken on the line 77 of ig. 2; Fig. 8 is a fragmentary rear elevation of the same parts under adiil'erent ad ustment with certain of them in section on line 8 of Fig. 1; Fig. 9 is a horizontal section taken substantially on line 99 of Fig. 2; Fig. 10 is a broken sectional rear elevation illustrating one printing position of the tally-roll strip with relation to the main paper carriage and as brought about through co6peration with the tabulating' equipment for said main paper carriage Fig. 11 is a similar view illustrating a dli, terent printing position of the tally strip.

as related to the main paper carriage and as brought about through similar coperation of parts; Fig. 12 is a detail illustrating operation of certain parts open return of the main carriage from the position illustrated in Fig. 11. o

The machine proper requires no description, being thoroughly familiar to those a skilled in the art, through extensive commer cial use besides which numerous patents have issued disclosing it in all of its details. Reference may be had in particular to certain of these prior patents which show various paper carriage equipments applied to this type of machine and more or less similarity to the equipment her shown and with which the tally-roll equipment of my invention cooperates. this connection attention is invited to Patent no. 1

913,738 dated March 2, 1909; Patent No. 924,118 dated June 8. 1909; Patent No. 929,056, dated July 27, 1909, and Patent No. 977,582 dated December 6, 1910.

Numeral 618 designates type plates such as commonly employed in Burroughs machines and the reference ral 1*2 desig- -h type plates are driven, said platen being mounted as usual in a cradle 18 mounted upon a carriage 19- which travels across the back of the machine upon a track 20. The cradle is here shown as carrying a holder 21 designed forgreceiving ledger sheets in fiat form whicli when droppedinto this holder will enter the bite between the roller platen and the pressure roller 22 (Fig. l) so as to be properly fed up roller. platen. The tally roll equipment is particularly useful in connection with ledger work and this'type of holder has been specially designed for the purpose of handling sheets in the fiat form, though it forms no part of my invention.

The tally-roll carriage of my present invention comprises a slide rod 30 which runs through lugs' 31 (Fig. 2) on the base of the machine proper and interposed lugs 32 on the back panel of the machine, the rod thus taking the place of hinge pintles ordinarily occupying the perforations of these lugs. This arrangement provides for minimizing the amount of projection of the tally-roll equipment at the rear of the machine. The tally-roll carriage further comprises lower side plates 33 and 34: having bosses embracing the said rod 30 and fastened thereto by set screws, said plates supporting between them the journal rod 35 of a take-up roller be noted that the tally 36 for the tally-roll strip.- A vertical plate 37 unites the plates 33 and 34 at their upper front portions and extends rearwardly between the plates on a downward inclination to the under side of the take-up roller 36, as shown in Fig. 4, this portion 37 of the plate supplying a. table over which the tally strip 40 passes. The said plate 37 extends upwardly along the back panel 2 of the machine through a space between the same and the carriage track 20 and carriage 19 and thence on up with a slight forward bend in front of the roller platen where it is curved in general conformity therewith and made with an opening 37 through which the tally-roll strip 40 passes from the front to the rear side of the plate, as clearly illustrated in Fig. 4, the type 618 being adapted to strike through said opening when the tally strip is in position to be printed upon. A second vertical plate 38 slightly spaced from the plate 37 and united therewith at the sides, forms with said plate 37 a flattened tube supplying a chute or guideway for said tally-strip in its passage downward from the roller platen. It will strip is in this manner completely enveloped by the metal of the tally-roll carriage in a space between the back panelof the machine and the main 'carriage trackj and carriage, so that said strip is thoroughly protected and exten-" sively "ded where it runs inclose rox- 'nhity to parts of the machine with relation on the turning of the- "that the tally strip is to which it shifts and there is therefore no opportunity for said strip becoming crumpled. or torn through encounter with such parts of the machine proper during the lateral shift of the tally-roll carriage or the main carriage. At the same time it will be noted that. the tubular construction increases the rigidity of this portion of the tally-roll which connects the take-up roll holder and the supply roll holder. The latter located above the roller platen is composed of side plates 37 c which may consist of bent-over portions of the same plate which supplies the before mentioned open-center curved portion 37". Thus this plate extends vertically from the curved portion as at 37 and the arms 37 are bent forward 'and support between them the rod or pin 39 on which the tally-supply roll 4.0 is mounted. In order to properly guide the tally strip from this roll down to the roller platen and guard it from being interfered with by any portion of the machine proper, there is fastened to'the supply roll holder a plate ll inclined with relation to the plate portion 37 d and having bent-over side pieces 41 screwed to the arms chute being thus supplied for the tally str1p to pass through. I The plate 41 terminates at the lower end just above the plate opening 37". before mentioned, and serves .to guide the strip easily into this opening. The tapered form of the above described therethrough when the tally-roll is initially arranged for use. To further facilitate in- 37,-a tapering troduction of the strip through its various 1 guides I prefer to make the opening 37 uninclosed at one side as shown in Fig. 3.- In addition to this the plate 38 is cut out in the center, as also shown in Fig. 3,. so that access may be had to the strip at this lower point if need be for working it down I through the lower chute.

It is desirable to make the tally-roll car-- riage as light as consistent with the necessary stability and it will be noted that I employ relatively thin metal plate in its makeup and keep down the width of the structure to approximately that of thestrip itself'throughout the major portion. The opening 37 must'of course be as wide as the strip and here I-provide a connecting offset plate portion 37 which may be reinforced by a rib or strip 37.

It will be seen that the above described construction of tally-roll carriage fulfils one of the objects primarily. stated, having reference to the avoidance of parts protruding laterally beyond the machine proper connecting upper and lower portions of the tally-roll carriage, while at the same time a thoroughly rigid construction is provided so kept in proper alinement; besides which it is so guided an for . said plate.

guarded that it cannot be interfered with by parts of the machine proper relative to which the tally-roll carriage shifts.

There is preferably mountedin the upper or supply roll holder a. pressure finger 50 to bear against the supply roll with enough friction to keep the strip taut as it is pulled from the roll. Said finger is secured to a rock rod 51 journaled between the arms 37 and is pressed against the roll by a spring 52,Fig. 3. A guiding roller 60 is journaled between the side plates 33 and 34: of the take-up roll holder in the corner 'where plate 37 and table 37* meet Fig. 4)

and the strip passes down in front of this roller and underneath .it and thence on to said table.

A pressure roller 61 bears against the take-up roller 36 being mounted vupon a journal rod 62 which occupies open slots m the said plates 33 and 34 and is supported by a pair of arms or levers 63 bifurcated at their rear ends to engage pivot studs 64 on the said plates, and connected at their rear ends by springs 65 with other studs 66 on I As a convenient means for taking the pressure off, if it should be desired to run the strip backward, I mount in said plates a rock. rod 68 having flattened portions forming thebaees of slots normally occupied by the aforesaid arms or levers 63. A handle 69 is fastened to one end of said rock rod and it will be obvious that by turning this handle the pressure roller may be forced out of engagement with the take-up roller 36. Between portions of the plates 33 and 34 which extend in rear of the said roller, a plate 70 is secured having a serrated edge by which; the strip may be severedat will after passing out under this plate and over the rod 68, from between the take-up roller and the pressure roller.

A spring 80 connected at one end to one of the lugs 32 and at the other end to the set tion (see Figs. 10 and 11) so that the said washer may be substantially flush with the main portion of the plate and a non-printing position of the tally-roll carriage fartherover. to the right thereby provided for.

The printing position of-the said tally-roll carriage is determined by abutment of a similar washer-85 (.Fig. 3) against the side of an arm 86 secured to one of the lugs 31, said washer being backed up by a sleeve 87 on the righthand end of the rod 3 0.

Referring next to the matter of increased facilities for shifting the tally-roll carriage aflattened forward portion of the bracket and extends out beyond the front of the machine where it is equipped with a handle 91*. In rear of its pivot the lever extends back to the righthand end of the rod 30 and has a bifurcated end embracing a roller stud 8" on the aforesaid collar or sleeve 87 The said'lever is a somewhat elongated piece of flat metal of angular form (Fig. extending alongside the machine below the operating handle thereof and it supplies a very convenient means'whereby the operator at will may shift the tally-roll carriage into and out of printing position. When this manual control of the tally-roll equipment is in use it is desirable that the spring shall be for the time virtually put out of commission. 1 therefore arrange not only for preventing the carriage from being accidentally shifted from its non-printing position, but through the same agencies 1 provide for its being detained in printing position when shifted to that position by the said hand lever. The before mentioned arm 95 86 is secured to the boss of a sleeve 86, (F 1g.

8) which has a drive fit in the bore of the adjacent stationary lug 31 so as to constitute a fixed support fora friction latch for engaging and detaining the rod 30- and consequently the whole tally-roll carriage. This frictionlatch is in'the form of a blade pivoted to the said arm 861(Figs. 7 and 8) and connected by a; spring 101 with a stud on a downward extension of said arm, which spring is adapted to cross the pivot of the latch when the latter'is thrown back and forth in order that it may serve to hold the same in operative or inoperative position. In Fig. 7 it is shown out of operative position and in Fig. 8 it is shown in section in operative position and in Fig. l it is shown in dotted lines,in operative position; When thrown to inoperative position it is limited by abutment of a tail 100 against the stud to which thelower end of thespring 101 is attached. The blade is Vshaped in cross section on its under edge and adapted to frictionally engage, V-shaped notches 30 and 30 in the rod 30. When engaged with the notch 30 this latch holds 7 the tally-roll carriage in printing position, the friction bemg suiiicient to prevent the spring 80 from returnmg the'carriage to anon-printing position. When the carriage is m nonprmting position and the blade or latch is in action it engages the other notch 30* and prevents accidental displacement of the tall '-roll carriage. When the latter is to he us (1 in a cooperative relationship'with the tabulating mechanism of the main paper carriage, then the said latch or blade is preferably thrown to its ineffective position shown. in Fig. 7, so that the spring may 5 serve to automatically return the tally-roll carriage to non-printing position. Referring next to the use of the tally-roll equipment as an automatic adjunct to the tabulating equipment, the latter is in the main the familiar one of the character disclosed in the beforementioned prior patents. It comprises a stop plate 105 (Fig. 2) mounted on the back panel 2 of the machine, and a rock rod 106 extending between the side plates of the carriage 19 and carrying a number of adjustable fingers 107 to cooperate with said stop plate for determining various columnar positions of the carriage. Said rock rod is both manually and automatically operable as usual',manually through the medium of a finger lever 108 (Fig. 1) applied to a crank arm 109 on the rod, and automatically through cooperation with elements of the line-spacing mechanism. The latter comprises the familiar cam 121 and lever 122 whose rear arm'operates upon the bifurcated ear of a plate 110 sliding vertically upon the back panel of the machine and having lugs 110 which underlie the cross-rod 111 of a line-spacing bail .which comprises arms "112 secured to a rock shaft 113. The latter has the usual connectionswith pawl-and-ratchet mechanism applied to the roller platen. Said bail another vertically sliding plate 115 whichis mounted against the plate 110 and is operated in unison with itor not according as line-spacing is to occur or not. The coupling and uncoupling devices between these plates is of familiar character comprising a dog or pawl 116 (Fig. 2) pivoted to the plate 110 and adapted to engage over a flange 115 of plate 115 under the action of a spring 117. The fingers 107 are of two difierent lengths which determine whether or'not line-spacing. willioccur when the carriage is in the columnar position fixed by abutment of the finger against the shoulder greater length will operate upon the said dog or pawl and hold it away from the flange 115 length will miss the dog or pawl. The. latter, besides serving as a coupler between 'the two vertical plates, also serves the familiar function of rocking the rod 106 by acting upwardly against the longer stop fingers when the plate 110 rises. The main e0 carriage is spring-drawn to the left (as viewed from the front of the machine) as usual through the medium of a tape or band 114 (Fig. 9) and spring drum 114.

For the purpose of effecting automatic co- 5 operation between such tabulating mechacross-rod 111 is embraced by jaws 115 of of the stop plate 105. Thus a finger'of the whereas a finger of the shorter nism and the tally-roll carriage, the rock rod 106,carries'one or more additional fingers 120 extending downward therefrom in stead of forward as do the fingers 107. In the present instance two of these fingers 120 are shown and a special construction of tappet piece on the tally-roll carriage, whereby provision is made for bringing the latter into printing position for two difl'erent columnar positions of the main carriage while at the same time providing for the re turn of the main carriage from the second of such tabular positions without being obstructed by the tally-roll carriage. To this end a tappet blade 130 is hinged to a plate 131 which is fastened to the side plate 34 of the lower tally-roll holder, and a spring 132 (Fig. 1) is-applied to the hinge to hold the blade 130. against said side plate 341 so that an upwardly projecting rear portion 130 of said blade above the side plate 34 will stand'in the path of the fingers 120 as illustrated in Fig. 1. When the main paper carriage shifts to a certain columnar position for which one of these fingers 120 has been set, that finger will strike against said upwardly projecting portion of the tappet blade and the tally-roll carriage will be ear-, ried along with the main paper carriage and brought 'to printing position. \Vhen thereafter the rock rod 106 is operated, either manually or automatically as before described, the said finger 120 will be swung out of line with the upwardly projecting portion 130 of the tappet blade, so that the main paper carriage may move'on to the nex-t.columnar position and the ,tally-roll carriage may return to its non-printing position. However, in this or some subsequent shift of the main paper carriage over to another columnar position, for which the second finger 120 has been set, this finger will operate against the tappet blade, in the same way that the first finger did, and again move the tally-roll carriage into printing position, as illustrated in Fig. 11. Upon the return of the carriage from this farther columnar position the first finger 120 is. permitted to pass by the tappet blade by reason of the hinge-mount ng of the same,

which action is. illustrated in Fig. 12. It will, however, be understood thatthe passby character of the tappet device is useful whether one or more than one special finger I is used on the rock rod for bringing the tally strip into printing position. .Thus when only a single one of these fingers is employed it would not necessarily come into play upon shifting of the main paper carriage to its last columnar position, but of course might come into play in shift of that carriageto some intermediate columnar position beyond which the carriage would move in a subsequent operation of the machine, carrying the single finger 120 beyond 13o the ally-roll tappet piece. In fact various situations may arise whichfwill call into play this pass-by character of the. tappet device. For example it may be that the opera tor will desire to move the main. carriage over to a certain columnar position for which a finger 120 has been set but without having that finger take the tally-roll carriage along, with the result that such finger would move over to a position beyondv the tappet piece. In the latter connection it will be noted. that the machine is so .de--

signed that the user may at will employ ,it for single column work in any columnar position of the carriage while at the same time having the tally-roll equipment available for the collection of any'items that he may desire to select from the list for purposes of subsequent checking over of the work. To adapt the machine for this sort of use the automatic tabulating mechanism should of course be disabled and the linespacing plates 110 and 115 kept coupled to gether. In the present instance a special key 110 is arranged at the righthand side of the keyboard (Figs. 1 and 5) and operates to disable the dog or pawl 116 and render effective a second coupling device 145 for the plates, not subject to displacement by a tabulator finger 107. Thus said key operates a thrust bar 142 extending across the back of the machine, which bar has a nose 14:2 to act against an upward extension 116 of said dog or pawl 116 so as to hold the latter out of position for rocking the rod 106, and said thrust bar has an upwardly projecting finger 14-2 for interlocking the coupler piece 145 with the plate 115. Said coupler piece 145 is pivoted to the plate 110 and normally held by a spring 146 out of engagement with the plate 115, as shown in Fig. 2. The latter plate has a notch 115 in one side and the coupler piece has a lug I l-5 to engage said notch, as illustrated in Fig. 3. The connections between the thrust bar 1 12 and the key 140 comprise a lever 117 pivoted to the inner side of the back panel 2 (Fig. 1 and dotted lines Fig. 3) and having an inclined slot 147 at its upper end engaged by a stud 148 on a laterally turned portion of a vertically movable horizontal bar 148 to which the stem 1 10 of the key 140 is coupled, as shown in Fig. 1. Said key stem is permitted a slight rocking movement in order that it may be latched down in the familiar way, to wit, by engaging a notch with the upper keyboard plate. It will be un derstood that when this key is used the tally-roll friction latch 100 will preferably be set so that the shifting of the tally-roll carriage will be entirely controlled by the hand lever 91.

i The tally strip 40 may, and preferably is, carbonized on the rear side for the purpose of ma'nifoldingupon the paper in the main nection serves for both tally strip and ink ribbon. I have shown a similar feed con ,nection without the ink ribbon equipment,

which connection comprises a ratchet wheel 150 on the take-up rollerBG, and a spring held actuating pawl 151 on a plate-lever 152 pivoting about the journal rod 85 of said roller and having a laterally projecting stud 1.53 adapted to be acted upon by the beforementioned feed-lever 122 of the regular line-- spacing mechanism. of the machine proper.

Formally said stud stands ofi' clear of said lever as shown in Fig. 2 but when the tallyroll carriage is shifted into printing position the stud moves under the lever as shown in Fig. 3.
